Eco-comfort technology makes these systems smarter in how they use energy and minimizes their impact on the environment. Plus there are many advanced features like the i-see™ Sensor, that automatically detects room temperature differences and adjusts for greater comfort. And Mitsubishi's triple filtration system dramatically reduces allergens.

Other updates to the line include a sleeker, lighter color finish and front access to the terminal block plus now there are new controls with a Smart Set button for ultimate comfort. And now the indoor units operate starting at a19dB(A). That sound is even quieter than a human whisper.

New technology revolutionizes the heat pump.

Unlike older, inefficient heat pumps, there is no cold air delivery with these systems. Larger coils heat faster, and the Hot Start system doesn't activate the fan until the desired temperature is reached so it never blows cold air. What's more, select Mitsubishi models use Hyper-Heating INVERTER (H2i®) technology that operates effectively down to -13º F. With this improvement these models give true year-round comfort from a single system.

These ductless air conditioners and heat pumps provide easy installation, simple service and longer warranties.

Mitsubishi Electric's units are easy to install with no ductwork. They're also designed for easy servicing although with their industry-leading reliability record, you won't have to worry much about that. Better yet, they've extended the warranties to seven years on compressors and five years on parts.
